What is the condition for resonance in an AC circuit? |
Card: 1 / 20 |
|
|
The inductive reactance (X_L) equals the capacitive reactance (X_C), i.e., X_L = X_C. |
Card: 2 / 20 |

|
Fill in the blank: The frequency at which resonance occurs is called ______. |
Card: 3 / 20 |
|
|
Resonant frequency |
Card: 4 / 20 |
|
|
True or False: At resonance, the impedance of a series RLC circuit is equal to the inductance L. |
Card: 5 / 20 |
|
|
False. At resonance, the impedance is purely resistive and equal to the resistance R. |

What does a high Q factor indicate about the resonance of a circuit? |
Card: 7 / 20 |
|
|
It indicates that the resonance is sharp and focused, with a narrow bandwidth. |

What is the formula for resonant frequency (f_r) in a series RLC circuit? |
Card: 11 / 20 |
|
|
F_r = 1 / (2π√(LC)) |
Card: 12 / 20 |

|
|
True or False: The quality factor Q is dependent on the resistance R in a resonant circuit. |
Card: 15 / 20 |
|
|
False. The quality factor Q is dependent on the inductance L and capacitance C, and is independent of resistance R. |

What occurs to the current in a series RLC circuit at resonance? |
Card: 17 / 20 |
|
|
The current reaches its maximum value, I = V/R. |
Card: 18 / 20 |
|
|
In a parallel RLC circuit, what condition must be met for resonance to occur? |
Card: 19 / 20 |
|
|
The inductive susceptance (B_L) must equal the capacitive susceptance (B_C), i.e., B_L = B_C. |
